Planning a month with weekly sheets
September 2027 spans 5 ISO weeks, 35 through 39, which means 5 weekly sheets if you print one a week. The first and last of those weeks straddle a month boundary, so a weekly planner will show days from August or October in the same row.
That is normal and it is why our weekly sheets print the month name on the first day of the week and again wherever the month changes mid-row. A planner that shows only the date numbers leaves you guessing at exactly the point where guessing is expensive.
